How to factory reset Kenmore microwave?
For Kenmore model 79080353310, our use & care information does not describe a single “factory reset” that restores every setting at once. The most reliable reset is to cancel the current cycle or cycle power, then re-set options (clock, sound, lock, demo mode) using the 79080353310 use & care manual.
Try these in order; they cover the most common control issues.
- Cancel a running cycle or clear an entry: Press STOP.
- Power reset: Unplug the microwave (or turn the breaker off) for about 1 minute, then restore power.
- Check Control lock: Use Clock & Settings to toggle Control lock On/Off.
- Check Demo mode: Use Clock & Settings to toggle Demo mode On/Off.
- Restore beeps/tones: Use Clock & Settings to toggle Sound On/Off.
| Reset method | What it typically fixes | What it typically does not fix |
|---|---|---|
| STOP key | Cancels cooking, clears a wrong keypad entry | Power loss, dead display |
| Power reset | Frozen keypad, odd display behavior, minor control glitches | Repeated fuse blowing, failed components |
| Clock & Settings toggles | Control lock, sound, demo mode, turntable options | Heating problems caused by internal electrical parts |
If the display is blank and nothing works after you confirm the outlet and breaker are good, an internal fuse can be a likely cause. For this model, a compatible replacement is the microwave fuse 5304509451.
- Disconnect power before any inspection.
- If a replacement fuse blows again quickly, stop and have the unit serviced; that points to an underlying electrical problem.
- If the unit runs only when the door is held a certain way, the door-interlock circuit may be involved; a compatible part is the microwave door interlock switch 5304509460.
“Factory reset” requests usually come from a locked keypad, a setting that was changed, or a control glitch. On model 79080353310, those issues are typically corrected by a power reset and the Clock & Settings options rather than a single master reset.

What causes Kenmore's microwave to stop working?
On Kenmore model 79080353310, a “stopped working” microwave is most often caused by a power supply issue (tripped breaker/outlet problem), a blown internal fuse, or a door interlock problem that prevents the unit from running even though the display may light. See the troubleshooting section in the 79080353310 use & care manual.
- Confirm the outlet works by plugging in a small lamp.
- Check the home breaker or fuse; reset if tripped.
- Make sure the door closes firmly and latches fully.
- Press STOP/CANCEL to clear a stuck setting, then try a simple 30-second cook.
- If the display is counting down but not heating, stop using it and move to the “heating circuit” section below.
| Symptom | Likely cause | What to check next |
|---|---|---|
| No lights, no display | Blown internal fuse or no incoming power | Verify outlet/breaker; then consider microwave fuse 5304509451 |
| Runs but won’t start when door closes | Door interlock switch or latch issue | Inspect latch alignment; consider microwave door interlock switch 5304509460 |
| Display works but unit won’t run | Door switch circuit, control issue | Check door closure and switches; control board testing may be needed |
| Runs but doesn’t heat | High-voltage components (capacitor/diode/magnetron) | Service recommended due to high-voltage risk |
These parts are listed for model 79080353310 and are common failure points:
- Microwave fuse 5304509451 (opens if there’s a surge or internal short)
- Microwave door interlock switch 5304509460 (prevents operation if it fails)
- Microwave door switch 5304509459 (part of the door safety circuit)
- Microwave thermal cut-off 5304509475 (opens if overheating occurs)
Microwaves use high voltage internally; a “simple” no-start symptom can be caused by a safety circuit doing its job. Using the correct troubleshooting steps helps avoid unnecessary parts replacement and reduces safety risk.

What size fuse for Kenmore microwave?
For Kenmore microwave/hood combo model 79080353310, the internal microwave fuse is part number 5304488359 (Sears PartsDirect part ID 5304509451). The exact amp rating is not specified in the model documentation we have for this unit, so we recommend matching the replacement to the original fuse by part number.
Use these checks before ordering or installing a replacement:
- Verify the model number on the unit’s rating label matches 79080353310
- Match the replacement by part number: 5304488359
- Compare the fuse’s markings (amps and volts) printed on the old fuse to the new one
- If the fuse is blown again quickly, check door switches and wiring before replacing it again
A compatible replacement for this model is the microwave fuse 5304509451.
| Item | For model 79080353310 |
|---|---|
| Replacement fuse identifier | 5304488359 |
| Sears PartsDirect part ID | 5304509451 |
| Where to verify specs | Printed on the original fuse body |
The microwave fuse protects the microwave from overcurrent conditions. If it opens (blows), the microwave may appear completely dead (no display), stop heating, or become unresponsive depending on what failed.
Microwaves contain high-voltage components that can store a dangerous charge even when unplugged. If you are not experienced with electrical repair, we recommend using a qualified technician.
For model-specific safety and access guidance, refer to the 79080353310 use & care manual.
